On-site density and concentration measurements in just a few seconds

Designed for on-site density measurements

• Leak-proof sealed housing to withstand rough conditions in industrial and field applications
• Additional rubber protection keeps the measuring cell safe
• Strong hard-glass front for a long working life
• Operated via capacitive keys with a sensitivity suitable for use with or without gloves
• Suitable for both left- and right-handed users
• Read RFID tags and start or abort measurements via gesture control: one hand is free to hold you steady when measuring hard-to-reach samples.
• For sample temperatures of up to 100 °C, supporting quick decisions, e.g. in the beer brewing process (measurement on hot wort)
• Smart patented oscillator connection (AT516421 B1) enables replacement in case of cell rupture

Intrinsically safe – for use in hazardous locations

• Intrinsically safe models DMA 35 Ex and DMA 35 Ex Petrol (Ex marking [Ex] II 2 G Ex ib IIC T4) for use in hazardous areas
• The only option available on the market for safe measurements in explosive atmospheres
• DMA 35 Ex is particularly suitable for measuring flammable chemicals.
• DMA 35 Ex Petrol is equipped with a special housing which provides excellent resistance to petroleum samples.
• DMA 35 Ex Petrol fully complies with the IP 559 and ASTM D7777 standards.

Fastest filling and measurement – for a huge variety of samples

• Fill all kinds of samples – no matter what the viscosity is – in one second using the built-in manual pump or a syringe.
• DMA 35 can also be used as a mini benchtop instrument; simply turn it upside down, put it on a table, and fill the sample up with a syringe.
• No expensive electrical wearing parts: you can easily do all cleaning and maintenance work yourself.
• Measuring cell with inspection window and backlight for convenient inspection of proper sample filling
• The most reliable portable density meter for fermenting beer or wine, due to intelligent oscillator placement (potential bubbles automatically move outside the measuring cell)
• Lock-position of pump preventing sample carryover
• Auto-rotating display for perfect visibility of results at any instrument position
• Influence of viscosity on your density result is automatically corrected: for reliable measurements, also on highly viscous samples

Perfect traceability of density and concentration results

• Storage of up to 250 sample IDs for easy sample identification
• RFID interface for changing measurement settings quickly by reading RFID tags
• Identify immediately if your products are out of spec: DMA 35 gives a color-coded warning if the measured sample is outside your accepted tolerance range.
• Storage of up to 1024 measurement results including time stamp and sample ID
• Wireless data exchange with a PC (csv or txt format) and data export to a printer via Bluetooth® for convenient data handling in the field – no extra software required
• Easy data management using optional license-free AP-SoftPrint program

Leave your glass hydrometer or pycnometer for a digital density meter

• Measurement directly at the sample container
• Requires only 2 mL of sample, filled via the built-in pump
• Preinstalled and programmable concentration units – no further calculations are necessary
• Each unit covers the whole relevant measuring range.
• Results available in seconds
• Perfect traceability of results
• Intuitive user interface without the need for any explanation

Quickly determining the state of charge of lead-acid batteries

• Determination of the specific gravity of sulfuric acid
• Used for measurement of sulfuric acid in lead-acid battery production and maintenance of uninterruptible power supply (UPS) systems
• Protection class IP54 and high chemical resistance for use in harsh environments
